It will be apparent froni the foregoing. that with the parts of my improvement posiv tioned as shown in Figure l, the dogs or handled as: a unit. Lwould' also have it understood that; I prefer to temper the lug "7' andfthe dogs or catches-10 in oil with a' catches 10 by cooperation witli the bolt 4 will strongly retain the lug 7 on the bolt sothat accidental displacement of the demountable V rim 3, will be re cluded.' I. When, however,

removalof the dernountable rim 3 is desired, it issimply necessary for an operator" to position-theimplement 14 as shown in Figure. 2-and"str'ike the outer end of the imple ment 14 with a hammer,- whereupon the dogs or catches -10iw'ill be moved outwardly or in. opposlte direction, and thesaid dogs or;

the bolt, the lug? may be readily removed for the-release of the 'demountable rim 3. Notwithstandingthe practical advantages I catches lbeingin that waydisengaged from I: from the wheel, and is provided with a plu ralityrofcircumferential ribsv 6, said ribs" being-convex in cross section at their outer w ascribed to my' improvement, it willbeapj preciated that the improvement issimple and inexpensive inconstruction and is to be re- ,lied upon for the strong retention of the lug on-the stud or bolt, and this Without interfering With the prompt removal of the lug when the same is desired.

I have specifically described the construe i ng circumterential ribs convex in cross section attheir outer sides, and dogs for cooption and relative arrangement of the parts embraced in the present and preferred embodiment of-lny invention in order to impart a full,,cleai' and exact understanding of the saidembodiment, I do not desire, however,
